To all w Imm. 'it muy concern Be it known that I, REiNHoin Sonunvr, citizen ot the German Republic, residing. at

Dusseldorf-Oberkassei, Germany, have invented certain new and useful Improvements in Time Stamps, of which the following` is a specification.

This invention relates to a time-stam with typewheels which are adjusted witii respect to clockwork driven stepped disks by vertically movable slides with .abutments or lugs 7 und more particularly to :i timestamp ot' this class in which the time stamp proper is separate from the clock-work p61'- f tion of. the stamp and need only be inserted into the clock-work casing in order to be properly adjusted, :is described in my prior Patent 1.137 2,91 l.

The invention consists in certain-improvementsin the safety-devices ot' the timestain-1p described in my prior potent to prevent unautlmrizod ,use yand wrong adjustment und comprises essentiallythe errungenient ot safety-devicesupon the hands ad- 1iustlnent and on the coupling between the clock und the gearing. aswell as a device 'for correctly adjusting the hour type yupon the stump, the provision of devices to en` sure the smooth intrmluction of the stump 3o into the bottom parLginy Order to effect the damping of the movement, for locking the type wheels in position.` as well as safety. de-

v vices against unauthorized use with Wrongl timey adjustment and against repented stampiugs successively, without fresh adjustment of the stamp.

The accompanying drawings illustrate two slightly dil'erentorms of the improved time-stamp. lu these show:

The clock-work 1 is arranged within a suitable casing' 2 and drives bythe projecting' minute shaft 3.a crank-pin 7 of the shaft 6 for-the stepped-disks 8., 9 and 10. The arrangement .and e function of these steppeddisksis already known bymy prior patent, as is the arrangement of'the movable slides 14, 15 `umd 16 with the abutments or lugs 1S and the upward extensions 19, 20 and 21. but theA abutment 18 of theslide 1G is in the presentcase adaptedito move laterally, to ensure :i safe transmission of the hour figune. as will be described more fully further Dis-v there is a tubular socket 73 within which a plunger 75 controlled by a spring le is slidably fitted, said plunger being within the reach of the edge of the disk 7G. Above the disk Z0 is disposed a double-armed lever 76 fulcrumed at Y?, the Iupper end ot' which is provided with an inclined plane 78 which extends into the open upper end 22 o'l' the easinp; 2 ot the stamp, into which end the casing` 23 ot the time-stamp proper is introduced 7When introducing the upper casing` 23 for thepurpose of adjusting` the type wheels to the e act time, the lever 76, as clearly shown in" Fig.' Q, is Yforced back against the resistance oi" the spring 79, whereby the 'forked lower end oil? the lever 76, the movement ot which can be accurately adjusted by means otftheset-screw 80, moves the diskf() vso far inwards that the pin 7 iS withdrawn from the recess 81 or' the dish 5, while simu taneously the pin 'or plunger 75 is itorced into one oil the recesses 82 of the stepped-disk 8., rthe recesses 82, which are sixty in number and which, vin accordance with the graduation ol'the said disk 8 ior minutes are disposed 'in a circle, are flared or provided with bevelled edges and Jfollow each other so closely that they touch, so that the pin 75 entering; a recess lacing` or almost tacing1 it locks the stepped-disks 8 or 9 in such a position, that the abutments 1 8 are always ofi-ered a solid contact surtace. j

Blythe withdrawal oit the pin 7 ,trom the disk 5, the connection between the clockwork and the stepped-disk gearing vis .cntirely interrupted. llereby the works o'l' the clock arev subject te wear and at .the same time the user of the stamp' is conipelled to withdraw "the upper casing inunediately after or soon after the'v introduction in the open end of the lower casing, as otherwise the` opening; 81 ot the disk 5 moves away from the pin 7 under the Ainfluence et the clock-work, so that the pin would then not be able to reenter the opening` again and a fresh adjustment oit the clock would be necessary. ln order to allow the vdisk a little play for the re-'introduction of the pin,

the edge et' the openingy is countersunk or bevelled, so that the pin 7 can enter the opening` 81 again although the disk has moved forward a little and the pin and hole do no longer exactly' coincide The adjustment of the clock iserlected by the button or knob 83 disposed at the back et the casing upon a sha'lit Upon 'the other end of the shaft 84s is lined a pinion 85 which `gears with awheel 86 carried by a lever Si" loosely j iivoted at its upper end upon the said shalt Elfi. The lever Si' is'iturzfiised its lower end with un angular piece` ed with whehby means `ot a spri C: `S9'it is drawn against a pin 91 provided with a c 'iical point at its 'other and-disposed ',vithin a guide 90. The pin 91 can be pressed back by the slotted shalt of a kei/92 which can be introduced into the casing through an opening 93, 'the edges of which are strengthened-by means ot slo'ttecl`-plates 94. These plates 94:" only allow the introduction ot a suitably shaped key. By pressing` back the pin 91 the lever Si' is swung around its tulcruin 84 and the wheel 86 is made to engage the teeth upon the disk 5 v-Jhereby tue turning` ot the clock-work by the button 83 is rendered possible. Unly the possessor ot the special key 92 is theretore in a position to setthe clock right.

A,its alreadymentioned, the abutment 18 oli the slide 16 lor the hours step-disk 10`is adapted to be moved laterally to enable itto act at the correct moi et ot the change trom one hour to the next. lt has been found that in other apparatusot this kind the passage from the last minute of one hour to the first minute of the next frequently does not take place early enough as in consequence ofthe slow progress ot the hours disk it happens that the `tens minutes or units minutes disk indicates the tiret minute of the nexthour while the hours disk still indicates the alreadyV passed hour. lt is sutlieient to cause this wrong` indication it the hours step and the corresponding abutment 155 just stand edge to edge.

'lo avoid this drawback an arrangementr has been made by means ot which the abutnient 1S .tor the hours .stepped-disk is moved little d tance sideways in the direction et the tresh hours step in case the first minute olf the tresh hour is adjusted by the tens j, -indes disk, so that the abutment in its downward movement is vpressed upon the correct step with certainty. To attain this result it is necessary to cutout the recessed edge of the stepped-disk 9 for joining with the nitty-ninth minute so deeply, that the abutment 18 for this stepped-disk when located above the recessed edge and being pressed down moved correspondingly liar down. By this deep depression et the abutment 18 of `the disk 9 the lateral displace- Vmention? the abutment 18 of the disk 10 is caused in the following' manner: The abutment 18 for the stepped-disk 10 is not firmly lined upon its slide 1(3,like the Vtwo other abutments 18, but upon a carriage 95 which by means of pins'96 is guided in slots 97 ot the slide 16 (see particularly Fig. The liront vertical end oit the abutment 18 .is situated in a groove 98 of another carriage 99 having guide slots 100 into which projects pins 101 on the corresponding` partil'on 13 (see in particular Fig. This cairiagje 99 is provided with a roller 10Qv engages a curved groove 1021i of the This groove 108 is so shaped that tor short motion ot the abutment- 178 for the stepped-disk 9, as owing,` to the shape ot this disk is the case with the minutes figures 10 to 9, the roller 102 remains unaffected, as the groove in the first part of its course is nearly straight. When however, the abutment 18 of the disk 9 passes over the recessed edge of the disk, it will during the introduction o1 the top casing be pressed so far downwards that the curved groove 103 causes a sidewise motion of the roller 102 with the carriage 99. The carriage 99 hereby also displaces the abutment 18 of the disk 10 which thus during its downward motion comes with certainty in contact with the next stepped-disk. As the deep recess of the disk 9 reaches up to the minutes figure 9, this advance of the abutment for the disk 10 will consequently be caused during the first nine minutes ot' the fresh hour.

The construction (of the type'wheel) for adjustn'ient 'for the tens minutes indications of the stamp in the upper casing is such that the variable depth of the steps is taken account of by the disk 9. As shown in Figures 9-14 the adjusting device for the type wheels is similar to the construction shown in my prior patent, inasmuch as here also the projections 88 on the lower ends of the slides coming in Contact with the extensions 19, 20 and 21 are displaced in correspondence with the position of the stepped-disks, Awhereby through the agency of the racks 34, the pinions 32 and the -pinions 30 and 29, adjustment of the type disks 26, 27 and 28 is etl'ected. The slides 35 are also provided with slots which are guided on bolts 37. The springs 39 for moving the slides into the shown final position are connected. however, in the construction illustrated with the shaft E8 ot theI wheels 230, 32 and hold these and therein.' the type disks in the zero position.

The extension 20 of the slide 15 for the tens minutes disk 9 is longer than the extensions 19 and 21, so that when the stamp or upper casing is introduced the extension 20 will come in contact with the appropriate projection 88 ahead of the extensions 19 and 21, and consequently will cause a sufficient lfnvnward motion of the slide 15 with the cin-ved groove 103, when the deepy recess of the disk 9 faces the appropriate abutment 18. It on the contrary less deep steps on the disk 9 face the abutment the tens minutes type disk will have a whole idle revolution impartedto it in consequence of the earlier contact ot' Vthe extension 20 with the projection :E8 of' the slide 35 tor adjusting the tens ininutes tvpe disk. whereupon only the adjustment proper oi the tens minutes types according to the position of the stepped disk takes pl ace.

The locking' of the adjusted type disks is cti'r-ected., as illustrated. b v bell-crank pawls 101. which engage with special ratchet wheels 105 fixed to the type wheels 20. 27 and 28 under the iniueuce of springs 100 which proj ection are fastened to the lateral arms 107 of the pawls 104. The arms 107 abut against the head 108 of the rod 109 which is pulled upwards by means of the spring L13 in the handle 211. The head 108 carries a lateral arm 11() having connected to it a pin 111 which is situated within the path ot a double-armed lever 112 disposed at the side or the casing 223. This lever 112 is furnished near its lower end with a square 113 which extends outward through a short slot 114 in the wall of casing A spring 115 has the tendency to maintain the lever 112 in the position shown in Fig. 10.

rThe square projection 11.2% engages a groove 116 in one side wall of the open end 22 of the lower casing when the stamp or top casing is introduced into the latter and slides in this lgroove 11G towards the right in consequence or' the shape o't the groove when the stamp is forced down. Hereby the lever 112 is caused to swing around its fulerum and pulls the head L08 down through the agency of the pin 111. The head 108 then presses against the arms 1.07 ot the pawls 104 and raises them Off the ratchet nf'heels 105, so that the springs 89 turn the pinions and on the shaft 83, and the pinions 29 and connected type wheels .into the. zero position. During the vtui-ther drnvn'uard motion oi the stamp or top casing the square projection 1.13 under the influence of the spring 115 engages with a tooth-shaped recess 117 ol: the groove .116, so that a premature withdrawal ot the Stamp prevented. while the square projection a'i'ter completion oit the dovvnward motion ot the stamp returns into itsl initial position owin;r to the shape ot the groove 110 and on withdrawal of the stamp rises vertically and thereby raises the guidepawl 118. Y

At the bottoni 119 of the open end olf the clock casing are provided a vertical slotted tube 120 and a vertical pin 121.. lVith the latter a pin 122 ot the introduced stamp or top casing comes in wontact, said pin 122'being attached to a slide 128 which kby means oi: slots is guided along one of the bolts 87, and another pin 121-. A rack 12V) at lthe upper part ol the slide 123 gears with a pinion 120 upon a shaft 12T. which slide under the Inlluence of a spring 1.28 is ordinarily maintained in the position shown in the drawing. 'lhe shattv is driven through a 'train ci: gear wheels connected with two winding wheels 129 and 130 lietween which. a pawlwlutch 132 is intercalated. the ratchet nnunber oit said clutch being mounted on a shaft "M The slide 123 is furnished with which engi.` in the Aon shown in Fig. 12 a pawl 184 rotatably mounted upon the bolt 3T and influenced by a .spring i 'Sii upon the pawl 184 with an inclined run.

ning up surface meets during the introduction oit the stamp or upper casing with the slotted tube 120 upon the bottom plate 119 ot' the open end oi the lower casing, whereby the pawl 1311 and thereby also the lever 135 with the locking pins 187 are moved out` ot the way so that the wheels 30 are now tree to rotate. During the Yfurther descent ot 'he stamp the pin 122 abuts against the pin 121 of the bottom plate 119 whereby the former together with the slide 128 are moved upwardly or inwardly or' the stamp. llereby the pinion 128 together with its shaft 12'? are revolved by the rack 125 of the slide 128 and thus the winding wheel 129 is driven through the intermediate wheels 189. Through the resistance caused hereby a desirable and suitable damping of the inserting motion ot the stamp is eected, so that the stamp cannot be damaged by clumsy handling. l/'Vhen withdrawing the stamp the spring 128 returns the shaft 127 again to its initial position, whereby also the slide 122i with the pin 122 again projects beyond the bottom plate of the stamp and is again locked in position by the engagement ot the pawl 1344 with the recess oil the slide 128.

its the pin 122 in this position prevents the use ot the stamp, the person intending to use 'he stamp must utilize the period of the reca-rn movement ot the pin 122. The user is thus obliged to press the withdrawn stamp down upon the ink pad and then immediately upon the article to be stamj ed. ln order that the time at disposal may not be too short, the return ot the slide 123 with the pin 122 must be retarded a little. its the winding wheel 129 does not sutlice tor the burpose, the second winding wheel '12:30 is inserted during the return, which then is driven by the pawl coupli 140 and a 'tui-ther intermediate gearing' 1111.

liilhen a large numberoi"l similar imprints are to be made, the pin 122 and the slide can be locked in trie withdrawn state. purjose a special tuliailar slit key introduced from the outside of cas- 28 into the upper end ot' the slot ot the rand slide 128, and 16. The hol tor this l 1= .'otected by means ot suitable httin s in a similar manner to the hey hole ior thcA ley 92 (see lEig.

The functions ot the various ysafety appliances as well as the manner of adjusting the type disks are briefly as follows:

On the withdrawn stamp ready for making the imprint, the time ttor which the stamp is set is maintained i, variable by the type disks, as the wheels 29, 30 are locked on the one hand by the pawls 10d and on the other hand by the pins 13"." on the lever 135. Any further imprint is also rendered impossible by the projecting locked pin 122. lililhen introducing the stamp into the open end of the lowerl or clock casing tor the purA pose ot setting the type wheels to the cor- -reet time for a further imprint, the slotted tube 120 oit thev bottom plate 119 first strikes the projection 138 on the pawl 13e, lifts it and simultaneously moves the pins 123i' ot the lever 135 out of engagement with wheels 30, so that now when the two pins 121 and 122 meet, the latter together with the slide will be moved upwardly or towards the inside, whereby the spring 128 will be subjected to tension and by 'turning the winding wheel 129 the desired damping or cushioning` ettect during the introduction ofthe stamp is obtained. Simultaneously the square pin 118 ot the lever 112 which has entered the groove 116 slides along the curve ot the groove 118, whereby the lever 112 is moved sideways and by the agency ot' the pin 111, projection 110 and the head-piece 108 the pawls 107, 104; are raised against the actioniot the springs 10G. llereby the gear wheels and type disks set entirely free, so that the springs 39 turn the shaift and thereby the slides with the abutments 38, as well the wheels 30, 32 and 29 with the type disks 28, 27, 28 into the zero position, whereby the guideslots oil the slides 35 :form the stop 'tor the final position or these parts. rlhe abutments 38 of theslides 35 which during the further descent ot' the stamp now meet with the extensions 19, 20 and 21 will then, after the abutments 18 have encountered the stepped disks 8, 9 and 10, be adjusted in accordance with the position of the latter, whereupon atter the downward motion ot' the stamp has come to an end the locking ot the adjusted type disks takes place by the pawls 104. rlhe square pin 118 ot the lever 112 at the bottom oli the groove 118 is pulled back into its initial position in accordance with the shape ot the groove, by the s lliiing 115, whereby the head 108` becomes tree and the springs 106 immediately pull the pawls 107, 10d against the locking wheels or ratchets 105. `After the stamp has been withdrawn the spring 128 by turning the shatt 127 draws the slide 128 with the pin 122 immediately again downwards. Sis, however, the winding wheels 129 and 130 sinniltaneousiy driven hereby retard this motion very much. there is suiiieient time tor pressing the stamp down upon the inling pad and ett'ecting the printing. The pin 122Which after the imprint pro to its farthest extent from the bottoni plate of theistamp, is now a ain locked in position by the pawl. .134; an by the simultaneously engaged pins 137 of the lever 135, the wheels30 are also again locked in position, so lthat an arbitrary setting of the type disks and. the further use of the stamp is prevented. y A

Upon the shaft 144 of the type disks 26, 27 and 28 there are disposed besides these time disks special type disks 145 for imprinting the date, which after adjustment are locked by means of a screw-pin 146. The head of the pin 146 is during'the introduction of the stamp guided in a longitudinal groove 147 in the open end 22 of the lower casing whereby in conjunction with the square pin 113 and a further pin 148 of the stamp, as Well as the corresponding groove 149 of the open end 22, the correct introduction of the stamp or upper 4casing into the lower or clock casing is insured.

In the modification according to Figs. 17 to 26 there is provided instead of the safety pin 122 of the first construction, a springactuated projection 150, which after the withdrawal of the stamp from the open end 22 and during the pressing down of the stamp upon the ink pad as well as during the subsequent imprinting is forced back against the resistance of the spring and then locked in position and prevents further iniprints being made. A further difference in the construction of the second form of the time stamp relates to the damping device provided in the lower casing of the timestamp. This device is here so constructed that during the introduction of the stamp its pin 148 meets with a lever 152 fulcrumed at 151 and forces it down against the resistance of a spring 153, whereupon simultaneously a segment 154 drives by counter gearing the winding wheel 155. After the Withdrawal of the stamp the spring 153 pulls the lever 152 back into the initial position.

The projection 150 is connected with a bar 156 extending into the interior of the stamp casing and with rails 157 and 158 guided within the casing. Springs 159, 160 pressing upon the upper part of these rails endeavour to press the rails and the projection 150 downwards or outwards. Thenecessary connection is formed by small pins 161 or the like.

The projection 150 is usually locked owing to a lever 163 lixed on a shaft 162 taking up such a position that it is situated just above the bar 156 and thus prevents the Abar with the projection from moving upwards (Fig. WTith the parts in this position the stamp can therefore not be used. Upon the shaft 162 at another place. there is fixed a further shortlever 164 which abuts against the upper end of a lever 166hinged to the rail 158 at 165, which by a spring 1.67 is held in the position shown in Fig. 22. Below the shaft 162 a further shaft 168 is disposed, upon which are iXed two segments with ratchet-teeth 169 and 170, against which the levers 163 and 166 abut with a -pawl 181 or 182. A spring 171 tends to turn the shaft 168 so that the segments are drawn against the pawls 181 and 182 of the levers 163 and 166. The lever 163 carries at the side a pin 180 against which reposes the arm 172 of a lever 173 rotatably mounted upon the bolt 37 and provided with pins 17 4 which engage the teeth of the wheels 30 and ordinarily lock them in position, similar' to the lever 135 in the first-described construction. One of the pins 174 is engaged bv a lever 176 fulcrumed at 175 and controlled by a spring 177. This spring presses the pins 174 into the teeth of the wheels 30 and hereby also the arm 172 of the lever 173 against the pin 180 of the lever 163. The lever 176 is provided with an inclined running-up surface 178 which during the introduction of the stamp meets with the slotted tube 120 of the bottom plate 119 in the open end 22 of the lower casing, whereby the lever 176 is pressed back against the resistance of the spring 177, lifting the pins 174 out of the teeth of the wheels Simultaneously the lever 173 with the arm 172 is rotated which by means of the pin 1.80 and the lever 163 imparts a slight angular motion to the shaft 162 (Fig. 26). Hereby the lever 164 upon the shaft 162 is moved and forces the lever 166 back, against the resistance of the spring 167 (Fig. 25). By the movement of the levers 163 and 166 their pawls 181 and 182 recede from the segments 169 and 170, so that the spring 171 is free to rotate the shaft 168 so far that the segment 170 is drawn against a pin 179, whereupon the pawls of the segments 169, 1,70 move past the teeth 181 and 182. After the removal of the stamp from the open end 22` the spring 177 presses the levers 17 6 and 173 back into the former position, so that the arm 172 recedes from the pin 180. The lever 163 is now in a position in which the projection 150 is at liberty to move inwards.

By the double forcing back of the projection 150 by pressing the stamp down on the ink pad and on the article to be imprinted, the lever 163 is again moved back into its initial position, so that it then again locks the projection 150 in position. During the forcing back of the projection, the tooth 182 of the lever 166 passes over the first tooth of the segment 1.70 and turns it during the rearward movement of the projection with the lever 1,66 forward by one tooth, whereby thetooth 181 of the lever 163 also engages the/first tooth of the segment 169 and the shaft 168 is held in a certain, slightly backward position against the resistance ofthe si if W1. The second forcing back of the p i eetion. (the imprinting) causes the lever .itin with its tooth 182 to pass over the secu ond tooth oit the segment 170 and to carry it alongv during the inward motionY o't the pro jection. In consequence the segment 169 is turned so lar that the tooth 181 of the lever 163 slides behind the second tooth ot the segment 169 and thus again comes into its locked position 'with regard to the bar 156. A further pressing back oif the projection 15() is now prevented and only possible after the release oif the lever 163 by the introduction oi1 the stamp into the open end 22 ot' the clock casing.

The projection 150 may be provided with an. appliance which forces the user to apply the stamp to the ink pad, as otherwise an indication becomes visible which shows that the ink pad has not been used.

It is obvious that the construction and arrangement ol the mechanism ,described may be variously modied Within the ambit of the claims Without departing from the spirit of the invention.
